1.42.0.0

plutus-core

Added

• Switch from cryptonite library to crypton (a drop in replacement).

• DropList builtin functionality

• Costing model for the DropList builtin

• A new type BuiltinArray.

• Three functions for working with BuiltinArray values:

  • listToArray (converts a list to a BuiltinArray)
  • indexArray (returns an element of a BuiltinArray by index)
  • lengthOfArray (returns the length of a BuiltinArray)

Fixed

• Fixed a bug in Plutus IR's dead code elimination pass that could incorrectly remove
  live data constructors or destructors.

plutus-ledger-api

Changed

• Remove un-needed dervied Typeable instances.

plutus-tx

Added

• PlutusTx.Function.fix, Plinth's equivalent of Data.Function.fix.

• Module PlutusTx.Optimize.SpaceTime, containing utilities for space-time tradeoff,
  such as recursion unrolling.

• Added PlutusTx.Data.List.null.

• Added PlutusTx.Optimize.Inline.inline. This works like GHC.Magic.inline, and can be used
  in the form of inline f or inline (f args).

• Added more functions to PlutusTx.Data.List.

Changed

• Remove un-needed dervied Typeable instances.

• Allow PlutusTx.Optimize.Inline.inline to inline local bindings.

• Removes the constructor id check from the code AsData generates for product types, resulting in better performance.

plutus-tx-plugin

Changed

• Changed the default value of compiler flag PlutusTx.Plugin:preserve-logging to true.

• The Plinth compiler now inlines fixed point operators by default. This can be turned
  off by using no-inline-fix or conservative-optimisation.

• The Plinth inliner now inlines local bindings (in addition to top-level bindings)
  with INLINE pragmas.

• AsData now avoids creating strict dead bindings (which were previously created for
  unused fields).

plutus-executables

No changes.
